Is 2mgo a solid?
Magnesium oxide (MgO), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide). Magnesium hydroxide forms in the presence of water (MgO + H2O → Mg(OH)2), but it can be reversed by heating it to remove moisture.

What is 2li?
H 2O – Water, oxidane. Other names: Water (H2O) , Hydrogen hydroxide (HH or HOH) , Hydrogen oxide show more. Appearance: White crystalline solid, almost colorless liquid with a hint of blue, colorless gas.
What is the mass of 2Li?
the molar mass of lithium Li2O is 6.9 × 2 = 13.8 g/mol.
What type of reaction is lithium and water?
Lithium reacts intensely with water, forming lithium hydroxide and highly flammable hydrogen. The colourless solution is highly alkalic. The exothermal reactions lasts longer than the reaction of sodium and water, which is directly below lithium in the periodic chart.
What kind of reaction is 2Li 2H2O → 2LiOH H2?
A single replacement reaction is when one element replaces another which is in a compound. For example, the reaction between lithium metal and water: Lithium + Water => Lithium hydroxide + Hydrogen. 2Li + 2H2O => 2LiOH + H2.
What type of reaction is 2 NaClO3 → 2 nacl 3 O2?
Type of Chemical Reaction: For this reaction we have a decomposition reaction. Balancing Strategies: To balance this reaction it is best to get the Oxygen atoms on the reactant side of the equation to an even number. Once this is done everything else falls into place. Put a “2” in front of the NaClO3.
